Yes. I cut one of the originals in half, right down the middle, from front to back, cut about a foot off the top and made new boxes from that. They were originally designed to be 3 feet wide and just small enough to carefully push through the doorway to my bedroom in Medina, Ohio.
Basically each one was the size of both of these pushed together face to face plus another foot on top.
They went from about 32 cubic feet down to a pitiful 12. But they are packed with glass wool and they sound really good.
Before the weather got bad, I refurbished them. I changed a tweeter, cleaned up the woofer cone, added regular speaker terminals to replace the quarter inch jacks, filled the scrapes a bit and repainted them. Good as new!
I got these woofers from Gary at Olson Electronics when it was still in Summit Mall! .... like 1985.
